- ing to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to water-closets, and more particularly to the Siphon type, although applicable to other types; and the chief object is to provide a compact and ef-y fective system of waterways for iiushing the' bowl and exhausting the Siphon or hopper, as the case may be, the same to be supplied directlyfrom a water-main, dispensing with an.

elevated tank such as ordinarily used with this type of closet-tf. e., a tank for each closetit being understood that it is within the purview of my invention to utilize a water-supply from a large general supply-tank.

Vith the above-stated and other objects hereinafter made apparent in view the invention consists in a number of novel features of construction and combinations of parts, all of which are recited in the appended claims, and a preferred form of embodiment of which is specifically described hereinafter with reference to the accompanying drawings, forming part of this speciiication.

Of said drawings, Figure I represents the closet in perspective as viewed from the rear. Fig. II represents the same in cross-sectional rear elevation. Fig. III iS a central longitudinal section. Fig. IV is a horizontal section taken on line IV IV of Fig. III. Fig. V is a central longitudinal section of a modified forni of closet, and Fig. VI is asection taken substantially on line VI VI of Fig. V.

The bowl a is of well-known form, being made with an overhanging flushing-rim a', and in the present instance the latter, in addition to having the usual discharge-holes in its under side, is formed with a number of holes a", extending downwardly through its inner wall at an angle of Jforty-tive degrees, so as to direct streams of water upon floating paper which might otherwise remain partially dry and fail to leave the bowl. The siphon l has its shorter limb h opening into the bottoni of said bowl, while its longer limb h stands vertically in rear of the latter and may have the usual sewer connection.

In the construction shown in Figs. I to IV the substantially triangular space between the limbs of the Siphon is closed by side webs b2, having circular openings, around which are formed cylinders c, standing out from said webs. IVaterways d and e open out of the upper sides of said cylinders, respectively, and extend vertically along the side webs and the sides of the Siphon, the waterway d being formed with a forward bend at its upper end and united with the flushing-rim, with which it communicates by the port CZ, while the waterway e is given an inward and slightlyrearward bend at the top, whereby it is carried over the dome of the Siphon and above the longer limb thereof, with which it com- 1n unicates through a jet opening or port e'.

The structure thus far described is ot' earthenware and produced by well-known meth-v ods. A metallic pipe j passes through the cylinders c and the space between the Siphonlimbs, said pipe having an annular flange j" taking over the end of one cylinder and a screw-threaded end portion protruding beyond the other'cylinder and receiving a capnut f2. Gaskets g are interposed between the cylinders and the flange and cap-nut, and when the latter is screwed home it will be apparent that water-tight closures are made between the metal pipe and the earthenware structure. The said pipe is formed in its' upper side withports t" and e, communieating, respectively, with the waterways d and e, and in its front side at the middle with a port j in registry with a port j', made through a thickened portion of the rear wall of the bowl, and beyond its flange the pipe is contracted Somewhat and unites with a valvecasing 7i, having on one side a screw-threaded nipple 72,', whereby a connection is effected with a water-main or water-supply conduit. A valve structure of an appropriate type is arranged within said casing to properly control the water-supply, the valve-stem being designated by the lgtter 't' and being jointed toone end of a lever e, which is pivoted in.- termediate of its length to abrack'et i2 on the casing and is equipped at the forward end with a handle i3 and a weight i to normally close the valve. A pull upwardly upon the said handle will open the valve and waterwill immediately rush into the pipefand thence up the waterways d and c, one stream discharging into the ushing-rim and the other into the dome of the Siphon, the result being that siphonic action is set up to exhaust the contents of the bowl while the latter is being flushed from the rim by the other stream of water. It will of course be understood that water stands normally in the bowl to the height of the short limb of the siphon, effecting a seal, and when the discharge has ceased a diminished supply of water through the flushing-rim restablislies such seal.

The establishment of the seal in the bowl insures a similar seal in the waterways CZ and e, for the reason that the small portsj and j afford communication between the bowl and the pipe f, the object of providing` said ports heilig to accomplish this result, which is importan-t, as the absence of a water seal in said ways would permit escape of sewer odors through the rim of the bowl.

In the construction shown in Figs. V and VI, the rear limb Z2 of the Siphon is not formed in connection with a horizontal sewerconduit in the earthenware structure, as before, but terminates some distance above the base-plane of the latter, and a swivel connection is effected between the same and a horizontally-extending metallic pipe 7u, so a discharge can be had in any direction desired. Said metallic pipe is formed with an upwardopening bell 7c', embracing the Siphon-limb and formed with an outstanding flange k2, against the under side of which iitsa flat ring m, apertu red atintervals to receive clampingholts m. These bolts extend through apertures in the flange m2 of a ring m3, surrounding the Siphon-limb and cupped to receive a rubber gasket m4, against which the flange k2 of the bell 7s abuts. By turning up nuts m5 on the bolts m below the ring m the gasket m4 will be forced into intimate contact with the siphon-limb in an obvious manner"` and a water-tight joint will be made. Upon loosening the clamping devices the pipe can he swung-in a horizontal plane to any desired position and again clamped to the siphonlimb, this pipe being preferably formed with a lug 7c to rest upon the surface above which the pipe extends. This construction of closet is particularly adapted to marine use, but may of course be utilized in other connections. In this modified form of closet there are no side webs closing the space between the limbs of the siphon, and consequently an earthenware cylinder c extends through such space to accommodate the metal pipef, such cylinder being integral with the rest of the earthenware structure and ported, as shown at d2 and e2, for communication with the waterways C Z and c and as shown at j for registry with the port j in the metal pipe.

The waterway d, instead of opening direct-ly into the flushing-rim, is shown in Fig. V as opening into a rellingchamber oz, formed between said rim and communicating by a port n with the latter and bya smaller port n2 with the bowl. The port n being at the top of the chamber the latter iills before the waterows to the rim, andthus a supply of water is retained, which eventually escaping through the small port n2 at the bottom of the chamber insures the relling of the bowl to the proper height after each action of the Siphon.

It will be seen that either ot the above-described constructions is well calculated to thoroughly fulfil the'object primarily Stated in addition to others herein stated; but at the Same time it is to be understood that the invention is capable .of embodiment in other forms than that here shown.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:
